                          INDEPENDENT AUDITOR'S REPORT

To the Shareholders and Board of Directors
Tridan Corp.

We have audited the accompanying statements of assets and liabilities of Tridan
Corp., including the schedules of investments in municipal obligations, as of
April 30, 2004 and 2003, and the related statements of operations for the years
then ended, the statements of changes in net assets for each of the three years
in the period then ended and the financial highlights (Note 6) for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights. Our procedures
included confirmation of securities owned, as of April 30, 2004 and 2003, by
direct correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and the financial highlights, referred
to above, present fairly, in all material respects, the financial position of
Tridan Corp. as of April 30, 2004 and 2003, the results of its operations for
the years then ended, the changes in its net assets for each of the three years
in the period then ended and the financial highlights for each of the five years
in the period then ended, in conformity with accounting principles generally
accepted in the United States of America.

                          NOTES TO FINANCIAL STATEMENTS
                             April 30, 2004 and 2003

Note 1 - Significant accounting policies

The following is a summary of the significant accounting policies followed by
Tridan Corp. (the "Company"), a closed-end, non-diversified management
investment company, registered under the Investment Company Act of 1940, in the
preparation of its financial statements.

Acquisition and valuation of investments

Investment transactions are accounted for on the date the securities are
purchased/sold (trade date) and interest on securities acquired/sold is included
in income from/to the settlement date. Investments are carried at amortized cost
in the Company's accounting records but are displayed at fair value in the
accompanying financial statements. Short-term investments are stated at cost,
which is equivalent to fair value.

Fair values for the Company's investments in municipal obligations have been
determined based on the bid price of the obligation, if available; if not
available, such value is based on a yield matrix for similarly traded municipal
obligations.

Amortization of bond premium or discount

In determining investment income, bond premiums or discounts are amortized over
the remaining term of the obligation.

Income taxes

It is the Company's policy to comply with the requirements of the Internal
Revenue Code that are applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no income tax provision is required.

Interest income from municipal investments are exempt from Federal and state
income taxes.

Cash and cash equivalents

The Company considers all investments that can be liquidated on demand to be
cash equivalents. Cash and cash equivalents, at April 30, 2004 and 2003, were as
follows:

                                                                 April 30,

                                                           $695,112     $555,844

At times, such amounts on deposit may be in excess of amounts insured by the
Federal Deposit Insurance Corporation.

                             April 30, 2004 and 2003

Note 1 - Significant accounting policies (continued)

Use of estimate

The preparation of financial statements, in conformity with generally accepted
accounting principles, requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Actual results could differ from those estimates.
Significant estimates are used in determining the fair value of investments.

Concentration of credit risk

The value of the Company's investments may be subject to possible risks
involving, among other things, the continued credit worthiness of the various
state and local government agencies and public financing authorities underlying
its investments. The Company and its investment adviser periodically consider
the credit quality of the Company's investments, and the Company adheres to its
investment objective of investing only in investment grade securities.

Note 2 - Accounts payable and accrued liabilities

Accounts payable and accrued liabilities consisted of the following at:

                                                                  April 30,

(a)   The Company utilizes the services of J.P. Morgan Investment Management,
      Inc. ("J.P. Morgan") as its investment adviser and custodian for its
      investments. The annual advisory fee is .28 of one percent of the net

                             April 30, 2004 and 2003

Note 3 - Investment transactions

Purchases and sales of investments in municipal obligations (excluding
short-term and demand investments) amounted to approximately $4,447,000 and
$4,484,000 for the year ended April 30, 2004 and $3,938,000 and $1,637,000,
respectively, for the year ended April 30, 2003.

The U.S. Federal income tax basis of the Company's investments, at April 30,
2004 and 2003, was approximately $35,801,000 and $35,937,000, respectively, and
net unrealized appreciation, at April 30, 2004 and 2003, for U.S. Federal income
tax purposes was approximately $2,393,000 and $3,433,000, respectively (gross
unrealized appreciation of approximately $2,455,000 and $3,435,000,
respectively; gross unrealized depreciation of approximately of $62,000 and
$2,000, respectively).

Note 4 - Common stock, share redemption plan and net asset values

At April 30, 2004 and 2003, there were 6,000,000 shares of $0.02 par value
common stock authorized of which 3,199,100 had been issued aggregating $63,982,
and additional paid-in capital aggregating $312,787.

The Company's share redemption plan permits "eligible shareholders" or their
estates to have their shares redeemed upon reaching age 65 or upon death. Shares
are redeemed at the net asset value per share, based on fair value, as of the
end of the Company's fiscal quarter in which the request for redemption is
received. At April 30, 2004 and 2003, $901,052 (77,227.5611 shares) and $853,280
(73,441.5208 shares), respectively, had been redeemed under this plan and are
held in treasury.

The net asset value per share is calculated by dividing the aggregate fair value
of all assets less the aggregate fair value of all liabilities by the number of
common shares outstanding at the end of the period.

The net asset value per share and the shares outstanding were as follows:

                                                                April 30,

Item 8.  Purchases of Equity Securities by Closed-End Management Investment
         Company and Affiliated Purchasers.

         Not applicable, because the registrant has no equity securities that

         1934

         (a)  The registrant's principal executive and principal financial
              officers have evaluated the registrant's disclosure controls and
              procedures (as defined in Rule 30a-3(c)) as of the end of the
              period covered by this report. Based on that evaluation, said
              officers have concluded that the registrant's disclosure controls
              and procedures are effective to ensure that information required
              to be disclosed in this report is recorded, processed, summarized
              and reported within the required time periods.

         (b)  Reportage on the registrant's internal control over financial
              reporting is not required until the report applicable to the
